digital signage GLOSSARY

LFD

LFD (Large-Format Display) is the industry term for commercial-grade displays from 32" upward, engineered specifically for digital signage and other professional applications. LFDs differ from consumer TVs in their thermal design, image-retention protection, anti-glare coatings, integrated remote management, and rated duty cycle (typically 16/7 or 24/7).

Major LFD vendors include Samsung, LG, Philips, NEC and Sharp/NEC, each with proprietary SoC platforms (Tizen, webOS, Android) that run signage software natively. Livesignage is certified across all major LFD ecosystems, providing a unified cloud platform that manages mixed-vendor fleets through a single workflow.

Use Cases

LFDs are the workhorse of professional digital signage:

- Retail in-store: 43"–55" displays for promotions and product information.
- Corporate: 55"–75" displays for lobbies, KPIs and meeting rooms.
- Hospitality: in-room TVs and lobby displays from major LFD lines.
- Healthcare: waiting room and patient information displays.
- Transportation and public spaces: schedule boards, wayfinding, public information.
